Today's cars and trucks have many lights that can come on the dash to warn the driver of a problem in a particular system. Many times when multiple lights are on, these can be related to the same problem.

Computers "TALK" to each other. So, a problem in one system can affect one or more other systems. Sometimes this will cause a system to be dissabled and the warning light to come on, even though that system does not have a probem.

A good example of this is that a problem in the ABS will usually cause the Traction Control to be dissabled. You may have an indicator that shows "TRAC Off". That does not neccesarily mean there is a fault in the Traction control function.

Does your car or truck have a warning light or indicator on the dash. Find out what these lights mean, what to do next, possible causes and solutions.

How Things Work

The front suspension absorbs the impact of the tires travelling over irregular road surfaces and dissipates this energy throughout the suspension system. This process isolates the vehicle occupants from the road surface.
